JOHN SNELL OHENHALLS, OF PLYMOUTH, ENGLAND.

VEHICLE-TIRE.

lPECIFIGATION forming part of Letters Patent No. 718,696, dated January 20, 1903.

Application filed March 4, 1902. Serial No. 96,664. (No model.)

To all whom it may concern.-

Be it known that I, JOHN SNELL CHEN- HALLS, engineer, a subject of the King of England, residing at 59 Ebrington street, Plymouth, in the county of Devon, England, have invented a new and useful Tire for Vehicles, of which the following is a full, clear, and exact description, and for ,which I have applied for Letters Patent in Great Britain, filed and dated August 16, 1901.

This invention relates to tires, and is especially applicable to autocars, motor-cycles, and similar vehicles.

The invention relates to that class of tire in which an outer wearing-piece acts upon an air-tube which is inclosed in the rim.

The present invention consists of a particular arrangement and combination of parts in a vehicle-tire which comprises inner and outer fellies, an air-tube arranged between said follies, and cheek-plates secured to the outer felly and riding upon the sides of the inner felly.

The invention is illustrated upon the accompanying sheet of drawings, upon which- Figure 1 is an elevation in cross-section of a tire constructed according to my invention.

Fig. 2 is a similar view showing the movement of the parts. Fig. 3 is an elevation in cross-section of a modification of the arrangement shown in Fig. 1.

The inner felly (b is preferably of Wood and is spoked in the usual manner. It is provided with a hollow b, forming a seat for the air-tube c. Around the air-tube is arranged an outer felly (1, also of wood, and to this felly d are bolted parallel cheek-plates e by means of bolts f, inserted transversely through the felly at intervals around the wheel. Both follies are solid or substantial and of rectangular section, and the parallel plates 6 and felly d thus form a whole which is also rectangular in cross section. The cheek-plates e are inturned at their outer peripheries to hold a rubber or other wearingpiece g, having a steel or other base h, it desired, in position. This wearing-piece 9 thus forms the tread of the Wheel. The inner peripheries ot' the plates 6 extend to the inner felly a. and ride upon the sides of the same, and the inner peripheries of the plates are at all times inward of the air-tube. It will thus be seen that while the inner felly a is fixed relatively to and at all times concentric with the hub of the wheel, the outer felly d is movable. (See Fig. 2.) The felly d rides upon the air-tube c, which is compressed. between the follies. The cheek-plates e are guided by the sides of the felly a. The plates 6 must be of such a depth as to prevent Water, grit, mud, and the like from entering the space between the fellies.

If desired and in order to strengthen the wheel, the felly a may have a metal portion 72,, in which the hollowb is formed. (See Fig. This figure also shows grooves j, rolled in the plates e intermediate of the depth of the same, and rubber tubing in position in said grooves. By this arrangement mud, 850., is more effectually prevented from passing into the space around the air-tube. Instead of rubber tubing rubber or leather cord or other packing material may be employed.

Metal shields 70 (shown in dotted lines on Fig. 3) in the form of rings may, if desired,

be arranged upon or recessed into the sides of the inner felly a to lessen the Wear of the plates 9 upon the felly a. v

The air-tube is preferably incased in a canvas bag and is fitted with an ordinary inflating and non-return Valve. The air-tube may be endless, or it may be a butted tube of the Bourdon type.

Having thus described my invention, what I claim as such, and desire to secure by Letters Patent, is-

1. In a tire for vehicles, the combination of a solid outer felly, of parallel cheek-plates rigid and flat upon the sides of said felly, of transverse bolts through said felly holding said cheek-plates to said felly, of inturned flanges to the parallel cheek-plates, of a rubber tread gripped by said inturned flanges and secured by said cheek-plates and said transverse bolts upon said outer felly, said rubber tread being narrower than said felly, of an inner felly separated from said outer felly by an air-tube, of a metal seating for said air-tube shrunk upon said inner felly, said cheek plates, outer felly, transverse bolts and rubber tread riding as one piece upon said inner felly and said cheek-plates extending inward of the wheel beyond the airtube.

2. In a tire for vehicles, the combination of a solid outer felly, of parallel cheek-plates rigid and fiat upon the sides of said felly, of transverse bolts through said felly holding said cheek-plates to said felly, of inturned flanges to the parallel cheek-plates, of a rubber tread gripped by said inturned flanges and secured by said cheek-plates and said transverse bolts upon said outer felly, said rubber tread being narrower than said felly, of an inner felly separated from said outer felly by an air-tube, of a metal seating for said air-tube shrunk upon said inner felly, and of metal shields inset in the sides of said inner folly and upon which the parts of said cheek-plates which are inward of the air-tube make rubbing contact.

3. In a vehicle-tire of the class described, the combination of an inner folly of wood, the rigid and parallel cheek plates 6, of grooves i in the plates intermediate of the depth of the same, of packing in said grooves, of shields 7c inset in the sides of the inner wooden felly, and of flat extensions of said cheek-plates e inward of said grooves and bearing upon said shields on the inner felly.

In witness whereof I have hereunto set my hand in presence of two witnesses.
